When it comes to air filtration in your home, it's important to know where the air filters are located. In most cases, the air cleaner housing is situated right next to the air handler of your heating or cooling system. This is a large metal box with a fan motor and fan inside, and it's usually found in the basement, attic, or utility closet. It's also likely to be close to your home thermostat, in a return duct.
In larger homes, there may be more than one HVAC system, each with its own filter. Start by looking for filters inside or near the HVAC unit itself. It's likely that these filters will be located next to the oven or air conditioner of the air conditioner. The HVAC unit can often be found in an attic, basement, or in the back of a closet.
Once you've located the unit, look for a hinged or removable cover approximately one inch wide. It can be oriented horizontally or vertically, and you should find a filter already in place. If you're not sure where your air handler is located, check the attic, basement, mezzanines, or garage. If you live in a smaller space (such as an apartment), your unit is likely in a closet.
Some homes are configured for air filters on the return grilles. Clogged filters require the system to put more effort into maintaining standard air circulation in your home.
